Here is a quick mnemonic “POLYSOMNOGRAPHIC STAGING“ to remember about Behavioral And Physiologic Correlates Of Sleep States

This can be valuable for patients as well as medical doctors, nurses & students doing their clinical rounds. You can also find it very useful for med exams like USMLE, MBBS, NEET PG, FMGE, NExT, MCAT & NCLEX exams

Behavioral And Physiologic Correlates Of Sleep States : How To Remember Easily ?

  • P – Polysomnographic staging of sleep correlates with behavioral changes during specific states and stages.
  • O – Onset of NREM stage N1 sleep inhibits the formation of short-term memories.
  • L – Lack of situational awareness is common among individuals aroused from transitional sleep stage (stage N1).
  • Y – Yes, certain disorders occur during specific sleep stages, such as sleepwalking, night terrors, and enuresis (bed wetting).
  • S – Sleep deprivation may cause transitions to intrude upon behavioral wakefulness.
  • O – Older men with REM sleep behavior disorder fail to maintain full paralysis during REM sleep.
  • M – Major physiological systems are influenced by sleep, including blood pressure and heart rate.
  • N – NREM sleep, particularly N3 sleep, is associated with a decrease in blood pressure and heart rate.
  • O – On awakening from REM sleep, individuals recall vivid dream imagery.
  • G – Growth hormone secretion is associated with N3 sleep in men.
  • R – Reduced firing of neurons occurs during sleep due to increased extracellular space in the brain.
  • A – Adequate sleep is important to prevent extracellular accumulation of β-amyloid peptide, a key step in Alzheimer’s disease pathogenesis.
  • P – Prolactin secretion is augmented during sleep in both men and women.
  • H – Hormonal secretion varies with sleep, including the inhibition of the thyroid-stimulating hormone and the cortisol axis.
  • I – Inhibition of melatonin secretion occurs with exposure to ambient light.
  • C – Circadian rhythms play a prominent role in the secretion of thyroid-stimulating hormone and adrenocorticotropic hormone-cortisol axis.
  • S – Sleep efficiency is highest when sleep coincides with endogenous melatonin secretion.
  • T – Thermoregulatory function is altered during sleep, with NREM sleep associated with a fall in body temperature.
  • A – Administration of exogenous melatonin can hasten sleep onset and increase sleep efficiency.
  • G – Gonadal hormone secretion, such as luteinizing hormone, is affected by sleep, with increased secretion during puberty and inhibition in postpubertal women.
  • I – In patients with sympathetic denervation of the pineal gland, melatonin administration may help improve sleep.
  • N – Neural connection from the retina to the pineal gland via the SCN mediates the inhibition of melatonin secretion by ambient light.
  • G – (blank)
